Bug Description

nova spec for cpu policy: http://specs.openstack.org/openstack/nova-specs/specs/kilo/implemented/virt-driver-cpu-pinning.html


"The scheduler will have to be enhanced so that it considers the usage of CPUs by existing guests. Use of a dedicated CPU policy will have to be accompanied by the setup of aggregates to split the hosts into two groups, one allowing overcommit of shared pCPUs and the other only allowing dedicated CPU guests, i.e. we do not want a situation with dedicated CPU and shared CPU guests on the same host."

Currently nova scheduler permits to set two different groups on the same host

It results, the following, pCPU attached to dedicated vCPU guests is shared with vCPU guest with
shared policy
